Hi all. I am using nRF5 SDK 15.0.0 and the S140 SoftDevice v6.0.0 to develop on an nRF52840. Due to software infrastructure constraints, I am unable to implement DFU using...
Hello,
I have a use case where I need to use UART_RTS and UART_CTS as GPIO for toggling the led. I also want to use the other two pins UART_TX and UART_RX for handling UART...
I have created an application that initiates a timer for 30 seconds and when it expires it calls an expiry function that switches the system off, if no button is pressed since...
If you try to write a program on a board with nRF5340 installed, an error will occur.
I can write to other boards using the same J-Link, so I don't think it's a J-Link problem...
Hello all,
I have scoured the devzone and other blogspots to find an answer to this but so far have come up short.
